fix: [257] unnecessary repetitive requests using the search bar

Assigning the search query value to the variable used to fetch the searched torrents is now done through
the onActivated hook, avoiding triggering the watchers, and thus, not making another unnecessary fetch request
to the back-end, getting the torrents only once.
